Jinergy persists in innovation-driven development, continuously increasing R&D investment to RMB 90.88 million in 2025, accounting for 4% of operating revenue, which exceeds the relevant standards for National High-tech Enterprises and Specialized, Refined, Unique, and Innovative enterprises, providing a solid financial foundation for technological breakthroughs. Furthermore, leveraging national and provincial innovation platforms such as the National Enterprise Technology Center and Shanxi Province High-Efficiency Solar Photoelectric Conversion Technology Innovation Center, the company has collaborated with the Shanghai Advanced Research Institute of the Chinese Academy of Sciences, Shanghai Jiao Tong University Solar Energy Research Institute, Nanjing University of Aeronautics and Astronautics, and other institutions to jointly advance the preparation and construction of the National Key Laboratory of HJT Photovoltaic Technology. The company has also successfully been included in the National Energy Administration’s “Racing to the Top” innovation platform list, forming an innovation consortium characterized by deep integration of industry, academia, research, and application, as well as coordinated efforts across the entire industrial chain.

Over the years, Jinergy has anchored itself in the high-efficiency photovoltaic technology direction, continuously strengthening the strategy of independent innovation in core technologies, and adhering to a rolling development model of technology iteration routes to ensure continuous iteration of technology reserves and drive the high-quality development of the photovoltaic industry.

Breaking through Challenges: Independent Intellectual Property and Strengthening the Foundations for Development

Core technology is the cornerstone for a nation and the “lifeline” of an enterprise. Jinergy has always insisted on keeping core technologies firmly in its own hands, regarding independent innovation as the lifeline of enterprise development. It continues to intensify patent layout and technology breakthroughs, building an independent intellectual property system covering the entire industrial chain.

In the company’s exhibition area of intellectual property, a set of figures stands out: the company has filed 437 national patents and obtained 263 authorized patents, including 40 invention patents. The patents comprehensively cover mainstream and cutting-edge technologies in the photovoltaic cell, forming a complete chain of independent intellectual property from cell structural design, core manufacturing processes, to the R&D of production equipment. The company’s innovative capabilities have been widely recognized within the industry, and it has received more than 100 science and technology achievement awards at various levels.

Among its many technological breakthroughs, indium-free HJT cell technology stands out as the company’s signature original achievement. As a rare metal, indium has limited resource reserves and significant price volatility, posing risks to industrial security and cost control. Through continuous optimization of TCO conductive film processes and material systems, Jinergy successfully achieves an indium-free technological breakthrough, developing a novel indium-free HJT solar cell structure and preparation method, for which it has applied for invention patents. This technology not only effectively reduces production costs, but also provides a new pathway for the domestic HJT industry to break free from dependence on critical materials and achieve healthy, sustainable development.

Robust technology not only supports the domestic market, but has also withstood the test of extreme environments in national major projects. On March 1^st 2025, China’s first large-scale new energy system at the Antarctic Qinling Station was put into operation. The system includes hardware facilities, such as wind power generation, photovoltaic power generation, energy storage batteries, hydrogen production, hydrogen storage, and hydrogen energy generation.

As an important part of this system, the specialized photovoltaic modules custom-designed by Jinergy for the Qinling Station have been successfully installed in Antarctica. Capable of stable power generation under harsh conditions, they provide efficient green electricity for the research station. This project serves not only as a “touchstone” for the company’s technical strength, but also demonstrates that the company can provide customized clean energy solutions for extreme environments around the world, making a transformation from a traditional production supplier to a comprehensive energy solution leader.

With its robust technology and quality, the company’s full range of high-efficiency photovoltaic products has successively passed authoritative domestic and international certifications, and been listed on the Australian Clean Energy Council’s recommended list.

By introducing advanced technologies such as the industrial internet, intelligent scheduling, and artificial intelligence, the company has achieved automation and intelligence across the entire process in material transfer, process flow and quality inspection. Relying on a full-process cost control system built on a digital platform, the company carries out precise matching and end-to-end traceability of the supply chain, establishing a dynamic cost monitoring model. Data shows that by using data-driven approaches to optimize production schedules, allocate resources, and reduce losses, Jinergy has lowered its photovoltaic module manufacturing costs by 18.32% year-on-year, further consolidating its cost advantages.

The localization of equipment is a critical step in reducing costs and ensuring the security of the industrial chain. The company has consistently addressed the bottlenecks and challenges in the industrial chain, focusing on key links, and taken the initiative to tackle “chokepoint” technological challenges with targeted solutions. The HJT magnetron sputtering equipment independently designed by the company achieved a major breakthrough. The domestically produced equipment has a production capacity four times that of imported equipment, with procurement costs at only half that of imported equipment, while cell conversion efficiency is actually 0.3 percentage points higher. To date, it has obtained 17 national patent authorizations. The company’s case of “Development and Application of Domestic Magnetron Sputtering Equipment for High-Efficiency HJT Cells” was successfully selected as a 2025 Shanxi Province Enterprise Innovation Case.

With leading technology, reliable quality and comprehensive service, Jinergy’s products have been exported to over 50 countries and regions including Japan, South Korea, France, and Chile, establishing the “Shanxi Intelligent Manufacturing” and “China Green Power” brands in the global market. Domestically, the company actively serves various scenarios, including large-scale photovoltaic bases, county-wide initiatives, and commercial and industrial distributed systems.
